5.7.3 Electrical Connectors
The following table describes the function of each connection and the type and ordering information for
connection. Certus OEM PCB Connector is the connector supplied on the Certus OEM PCB ready for customer
connection. Mating Connector for Cables is the manufacturers mating connector and part number, plus the part
number for a pre-crimped 15 cm cable.
This information is provided to make it easier for you to design the appropriate type and length of connections
for your specific application. To make development easier, we also provide standard ~30 cm pre-prepared as
described in section 4 Part Numbers and Ordering
